Stanford researchers have found that lack of exercise may be the reason obesity rates are rising in the United States. A new study from Stanford found that people are eating about the same amount of food they were eating 25 years ago, but they’re exercising less, which correlates with the country’s collective weight gain –more than two thirds of U.S. adults are considered obese or overweight. Dr. Uri Ldabaum is an associate professor of gastroenterology and lead author of the study. He joins us to explain more about the findings, which will appear in the August issue of The American Journal of Medicine but is available online now in a draft form.

A cardiac wellness program for people with no insurance? Dr. Tissa Kappagoda, a former Director of the UC Davis Cardiac Rehabilitation Program, has created a new plan to educate and help people before a major heart problem occurs or after their hospital-based rehab has ended.

This pilot program is housed now on the CSUS campus and could become a model for similar programs across the country as Dr. Kappagoda explains.

There is no website for this program but if you would like more information contact
